Abstract
The previous reports showed that vegetable matters contained in a wool sliver could be eliminated by the hydrolysis method using dilute sulphuric acid, even if it did not undergo the process of baking and crushing.As the following step of the study, an attempt has been made to carbonize a first gilling wool sliver by an industrial method carreid out in the system of backwashing machines.As a result, it has been proved that most of the vegetable matters contained in a wool sliver is hydrolyzed into considerably fragile substances which can ultimately be crushed into powder when they go under the process of gilling and combing. This method makes it possible to remove approximately 95% of the impurities contained in raw materials when treated in a popular way used in most spin ning mills.In addition, this method appears to have scarcely any unfavorable influence on fiber properties, i.e., fiber length, tensile strength, alkali-solubility, dyeability and colour-fastness of wool.
